2 Claims. (CL 146-73) This invention relates to a roll, biscuit and bun slicing machine and has for one of its objects the production of a simple and efficient machine for efficiently slicing biscuits, buns, rolls and similar small breads, in a manner to eliminate hand slicing.

- A further object of this invention is the production of a simple and eflicient slicin machine which is so constructed as to facilitate the selective slicing of a biscuit, bun or roll, either partly through or completely through.

- Another object of this invention is the production of a simple and efficient slicing machine wherein the sections thereof are removably mounted upon a supporting base in a manner whereby the sections may be readily separated for the purpose of cleaning.

Other objects and advantages of this invention will appear throughout tion and claims.

a In the drawings:

Figure 1 is an edge elevational view ing machine;

Figure 2 is a side elevational view thereof;

' Figure 3 is a vertical sectional view taken on line 3-3 of Figure 1;

Figure 4 is a vertical sectional line 4-4 of Figure 2;

Figure 5 is a perspective view of the main casing of the machine separated from the base and motor casing, a certain portion of the side wall being broken away; 7

Figure 6 is a perspective view of the motor casing and cutting knife;

Figure 7 is a perspective view of the base;

Figure 8 is a perspective view of the removable bun abutment slide;

Figure 9 is a fragmentary vertical sectional view of the machine showing the bun abutment slide in an operative position; and

Figure 10 is a fragmentary side elevational view of the cutting knife and supporting motor shaft, showing the manner of locking the knife upon the shaft.

By referring to the drawing, it will be seen that H] designates a base which is adapted to rest upon a table or other support H in a manner to overhang the support, as shown in Figure 1. The base It) is substantially T-shaped having a central motor casing supporting portion l2 and an elongated right angularly extending main casing supporting portion B. The portions l2 and I3 are provided with inset upstanding retaining flanges or ribs M, as shown in detail in Figure 7. A motor containing casing is supported upon of the slicview taken on the following specifica the portion [2 and a retaining strip l6 engages the inner face of the wall I! of the motor casing l5 to anchor the same against the adjoining flange or rib I4, as shown in Figure 4. An elec-' tric motor H! of a, suitable type is supported in .any desired manner within the casing I5 and carries a projecting driving shaft l9 which extends into the main chine is assembled. A knife disca2l is adjust? ably locked upon the outer end of the shaft l9 by means of the nuts 22 which fit upon oppositesides of the knife disc 2|, as shown in Figure 10. The knife disc may be adjusted to the desired position upon the shaft nuts 22, as will be obvious, to the main casing 20.

The main casing base l0 and the lower end thereof rests upon the elongated portion I2. The flanges l4 assist in retaining the main casing in a detachable anchored position upon the base ID. This main casing 20 preferably comprises an upright body which is rectangular in cross-section having an open top 23 and an open bottom 24. The casing 20 also is provided with a side opening 25 upon one side thereof which terminates short of the top thereof to snugly receive the adjoining side of the motor casing l5 which is of a desired contour to snugly fit into the opening 25. Vertical anchoring pins 26 are carried by the motor casing [5 at the top thereof adjacent the side which fits into the opening 25 of the main casing 20 and this main casing 20 is provided with an overhanging anchoring flange 21 at the top of the opening 25. The flange 21 is provided with spaced apertures 28 for receiving the pins 26 to hold the main casing 20 and the motor casing IS in' locked assembled position. 1 1 When assembling the sections of the machine; the base [0 is placed upon a support and secured in position in any suitable manner. The motor casing I5 is placed upon the portion l2 of the base, and the main casing 20 is dropped down over the knife 2| so that the apertures 28 of the flange will fit over the pins 26 and thereby anchor the casings l5 and 28 in assembled relation, the flanges 14 holding the casings in a fixed position upon the base l0.

It will be noted by considering Figures 3, 4 and 5, that the casing 20 carries a vertical partition 28 which is slightly offset from the center toward one side edge of the casing 20 to avoid obstruction of the shaft l9; note Figure 3. This partition 29 is provided with a vertical aperture or slot 30 for receiving the knife disc 2|. An inwardly exproperly fit within casing 20, when the ma-.

[9 by adjusting these tending and downwardly inclined panel 3| extends from the upper side edge of the main casing to the upper end of the partition 29, which pare tition is inset at its upper end relative to the upper entrance end 23 of the casing 20. This panel constitutes a chute to deliver the buns, rolls, etc., to the cutting compartment 32 into which the cutting knife 2| extends, as shown in Figure 3. When it is desired to cut the bread products. ch as bun s, r b sc t e lr partly through in hinge style, the bread products are rolled down the chute or inclined panel 3 I in the direction of the arrows shown in Figure 3, and as the knife disc 21 revolves, the bread, products will be forced against the edge panel 20 while the knife disc 2| cuts them to the desired depth. The bread products will then 6129p (20%; through the open bottom 24 and through the apertures 32 in the base H! where they will fall into a suitable container 33, as shown in Fi ure 1-.

Where it. is desired to. cut the b ead nm l fiii such as buns, rolls or biscuits entirely thro h #9. provide two separate halves, a removable abut..- ment slide 3.4 is ,t ended vertically between the inner face of the abutment wall 2% nd the. edge of the knife. disc it, as shown in. Flam 9- slide 11 preferably comprises an. abutment panel 35 and a pair of longitudinal side ribs 35-. A transverse ledge strip 81: is carried ne r the. u per end of the slide 34 to overhang the ur n -r the main casing 2d, and act as a support and fulcrum therefor. The slide BA; is provided a, protruding tongue 38 at. its upper end; to ggQili q tatethe placing of the. slide 34. n P sition and in manipulating the same. Shotdd the slide 3}. become worn, or fail to. fit. to cause the bread products to e completely ant through the slide 34-. may be tiled QOWMQ 5 3. edge of the. knife disc at by swin in the slide. at. upon. the fulcrum flan e or led e strip fl.

Erom the foregoing description. it w l e $23 that the bread products. may be easily? cut. hinge style, or by inserting the 3.4. ha articles may be easily. cut in half. Furthermore, the motor; casing I15. and the main casing 211: may be easilyremoved from; the base l0 fop easy cleaning to. comply with the sanit r require ments of various health depar ments. Since the sections are. removable, this will taeilitate the repair or replacement of parts, and if so, desired, the motor case. 15. may be removed trees. ease-serment with the casing 2 a buf r Q1 polisher may.- replace the; kniie didQ: 21,. i d tor the pu p s of polishing silverwax a 8. 2 (lee also. may r plac the knits disc 21 t sharpen knives and the like, without departin item the spirit of the invention. It should; be, that, t e Present. device may tens d. for; cuttin ei h the round t pe. Qt as. shown.-

an to hold the main casing and motor casing against:

4 the elongated type as shown in Figure 9-, or infact it may be used in cutting any suitable product, without departing from the spirit of the invention.

Certain detail changes in the mechanical structure may be made without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.
